Stars Who Work With Their Exes

Breezy and Rihanna's relationship has been anything but simple since an incident following the 2009 Grammys that left Rihanna's face beaten black and blue and Chris convicted of felony assault. Against all odds, the onetime lovers reunited almost exactly three years later to collaborate in the studio. CB recorded a rap for the remix of Rihanna's "Birthday Cake," singing such romantic lyrics as "Girl, I wanna f--- you right now" and "I've been missing your body." Rihanna, in turn, belted out, "I love you, baby," on the remix of Chris' "Turn Up the Music." When the exes showed up at the 2013 Grammy Awards together, they left no one wondering anymore about their romantic reunion.
